The silver pumpkin looking thing is the rear differential. The picture is set up so the top of the picture is the rear of the car, the bottom is the front.
At the bottom of the differential(the front side of it) is a black tube which is the driveshaft. It connects to the differential with a black rubber coupler disc. See how close the one exhaust pipe on that car comes to the rubber disc?
